apps/calendar/ajax/events.php in ownCloud before 4.5.11 and 5.x before 5.0.6 does not properly check the ownership of a calendar, which allows remote authenticated users to download arbitrary calendars via the calendar_id parameter.

The contacts application in ownCloud before 4.5.10 and 5.x before 5.0.5 does not properly check the ownership of contacts, which allows remote authenticated users to download arbitrary contacts via unspecified vectors.

ownCloud Server before 7.0.8, 8.0.x before 8.0.6, and 8.1.x before 8.1.1 does not properly check ownership of calendars, which allows remote authenticated users to read arbitrary calendars via the calid parameter to apps/calendar/export.php.

The virtual filesystem in ownCloud Server before 6.0.9, 7.0.x before 7.0.7, and 8.0.x before 8.0.5 does not consider that NULL is a valid getPath return value, which allows remote authenticated users to bypass intended access restrictions and gain access to users files via a sharing link to a file with a deleted parent folder.

lib/base.php in ownCloud before 4.0.8 does not properly validate the user_id session variable, which allows remote authenticated users to read arbitrary files via vectors related to WebDAV.

ownCloud Server before 5.0.16 and 6.0.x before 6.0.3 does not properly check permissions, which allows remote authenticated users to read the names of files of other users by leveraging access to multiple accounts.

ownCloud Server before 4.5.7 does not properly check ownership of calendars, which allows remote authenticated users to read arbitrary calendars via the calid parameter to /apps/calendar/export.php. NOTE: this issue has been reported as a cross-site request forgery (CSRF) vulnerability, but due to lack of details, it is uncertain what the root cause is.

The documents application in ownCloud Server 6.x before 6.0.6 and 7.x before 7.0.3 allows remote authenticated users to obtain all valid session IDs via an unspecified API method.

The document application in ownCloud Server before 6.0.3 uses sequential values for the file_id, which allows remote authenticated users to enumerate shared files via unspecified vectors.

Incomplete blacklist vulnerability in lib/migrate.php in ownCloud before 4.0.13 and 4.5.x before 4.5.8, when the user_migrate application is enabled, allows remote authenticated users to import arbitrary files to the user's account via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.15, 4.5.x before 4.5.11, and 5.0.x before 5.0.6 allow remote authenticated users to inject arbitrary web script or HTML via the url parameter to (1) apps/bookmarks/ajax/addBookmark.php or (2) apps/bookmarks/ajax/editBookmark.php.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.16 and 5.x before 5.0.7 allow remote authenticated users to inject arbitrary web script or HTML via vectors related to shared files.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.15, 4.5.x before 4.5.11, and 5.0.x before 5.0.6 allow remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

Multiple cross-site scripting (XSS) vulnerabilities in js/viewer.js in ownCloud before 4.5.12 and 5.x before 5.0.7 allow remote attackers to inject arbitrary web script or HTML via vectors related to shared files.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud 5.0.x before 5.0.6 allow remote authenticated users to inject arbitrary web script or HTML via the (1) tag parameter to apps/bookmarks/ajax/addBookmark.php or (2) dir parameter to apps/files/ajax/newfile.php, which is passed to apps/files/js/files.js.

Cross-site scripting (XSS) vulnerability in the import functionality in the bookmarks application in ownCloud before 5.0.18, 6.x before 6.0.6, and 7.x before 7.0.3 allows remote authenticated users to inject arbitrary web script or HTML by importing a link with an unspecified protocol. NOTE: this can be leveraged by remote attackers using CVE-2014-9041.

ownCloud Server before 7.0.12, 8.0.x before 8.0.10, 8.1.x before 8.1.5, and 8.2.x before 8.2.2, when the "file_versions" application is enabled, does not properly check the return value of getOwner, which allows remote authenticated users to read the files with names starting with ".v" and belonging to a sharing user by leveraging an incoming share.

Cross-site scripting (XSS) vulnerability in the activity application in ownCloud Server before 7.0.5 and 8.0.x before 8.0.4 allows remote authenticated users to inject arbitrary web script or HTML via a " (double quote) character in a filename in a shared folder.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud before 4.0.12 and 4.5.x before 4.5.7 allow remote authenticated administrators to inject arbitrary web script or HTML via the (1) site_name or (2) site_url parameter to apps/external/ajax/setsites.php.

Cross-site scripting (XSS) vulnerability in settings.php in ownCloud before 4.0.12 and 4.5.x before 4.5.7 allows remote administrators to inject arbitrary web script or HTML via the group input field parameter.

Multiple cross-site scripting (XSS) vulnerabilities in ownCloud 4.5.x before 4.5.8 allow remote authenticated users with administrator privileges to inject arbitrary web script or HTML via the (1) quota parameter to /core/settings/ajax/setquota.php, or remote authenticated users with group admin privileges to inject arbitrary web script or HTML via the (2) group field to settings.php or (3) "share with" field.

The login page (aka index.php) in ownCloud before 5.0.6 does not disable the autocomplete setting for the password parameter, which makes it easier for physically proximate attackers to guess the password.
